I have a 150w 20" sunpod and was wondering if it would be good for a coral tank i was looking about setting up. I was thinking about buying a 20 gallon tank, but i wanna know is that light gonna be good for coral?

what would be the best GPH in a tank that size because i have a overflow filter with a 175 GPH pump (go smaller maybe?)
